How to use index map from Create Set to 'accumulate'

Here’s one approach…

Split intersecting Splines. Sift and Entwine

Well I took a moment to look at the intersection component again and actually all information is there. In case non-intersecting curves are involved, a collision check is required. The iA and iB outputs show which item in the list of curves intersect. These indeces correspond to the path structure of the C input. Replace path can be used to assign the path to each timestamp tA and tB. There’s also a component called treefrog to assign paths to assign paths to items but the solution below works…
